Patented Nov. 8, 1949 UNITED STATES "PATENT OFFICE ,2,487,444 SUC'IION BRUSH FOB VENETIAN BLINDS Julian M. Ines.' Norfolk, Conn. applicati October 25, 1945, Serial No. 624,405 1 Claim. (Cl. 15-390 The present invention relates to new and useful improvements in brushes and more particularly to a brush essentially adapted for cleaning the slats of Venetian blinds and the like, and the invention has for itsv primary object to provide a brush of this character embodying means for connection-with a suction device whereby dust removed from the slats during the brushing operation may be drawn into the hose of a vacuum cleaner or similar suction apparatus.

A further object of the invention is to provide a brush of this character which is effective for simultaneously cleaning both sidesv of the slats of Venetian blinds.

A still further object is to provide a brush head embodying means for removably mounting brush elements therein wherebyto facilitate renewal of the brushes when desired.

A still further object is to provide a device of this character of simple and practical construction, which is neat and attractive in appearance, efficient and reliable in operation, relatively. -inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Otherobjects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereoL'wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the brush showing the same applied to a Venetian blind slat for cleaning the same.

Figure 2 is an enlarged side elevational view zontal slot or opening 0 in its front edge and continuing along veach side edge for the greater portion of the latter. A tubular shank I is formed at the rear edge of the head and communicates with the interior of the head. A suction hose 8 of a conventional vacuum cleaner is detachably connected to`the shank.

Upper and lower brush holding plates 9 and I0 are secured in the upper and lower portions of the head by bolts or the like I l, each plate being concaved to conformably seat in the head and having curved channels I2 along `their side edges of dove-tail shape in cross-section. The channels of the upper and lower plates are opposed t0 each other and project outwardly from the sides of the plate to provide shoulders for resting on the side edges of the slot t of the head to thus bring the side edges of the plates flush with the sides of the head.

Figure 3 is a front elevational view.

Figure 4 is a longitudinal-sectional view taken substantially on a line 4--4 of Figure 3.

Figure 5 is a sectional view taken on. a line 5-5 of Figure 2.

Figure 6 is a transverse sectional view taken on aline 6-8 of Figure 2.

Figure 'I is a group perspective view of one of the brush mounting plates and the brush element removably mounted therein, and Figure 8 is a side elevational view of the brush head with the brushes removed.l

Referring now tothe drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral ii designates a hollow brush head of adapted for attachment to and lower brushes contacting each other.

Arcuate brushes i3Y having dove-tail shaped backing plates Il are positioned in the channels by sliding the backing plates in one end of the channels, the ends of the bristles of the upper The front ends of the brushes Il are spaced apart. from each other to provide an opening therebetween and through which dust may be drawn into the head and hose by the vacuum cleaner.v

By inserting the edges of a Venetian blind slat I5 between the brushes I3 and sliding the brushes along the slat, the slat may be cleaned of dust which is then drawn into the head.

The brushes I3 may be removed and replaced after becoming worn.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully compre-v hended by the spirit of the invention as herein described and the scope of the appended claim.

What is claimed is:

A suction cleaning brush for slat blinds comprising an elongated hollow head substantially circular in cross section andhaving a rear end a suction hose, said head having concavo-convex opposed portions Substantially Circular design and having a hori- 56 and a L'shaped slot extending from the front a clear understanding of the 4 end of the head along said head at opposite sides REFERENCES CITED thereof and separating said portions, whereby said portions are adapted to straddle a slat inmhf {gwmgferens are of record in the serted in said slot. a pair of opposed plates in p9' said head tting conformably against said por- 5 UNITED STATES PATENTS tions with shoulders fitting against the edges Number N `of said slot, and each having a pair of dove- 1,237,047 Howelnu,-..
